‘壹’ python模拟登陆12306，该怎么处理

给你个我之前写的参考
import re;
import sys;
import cookielib;
import urllib;
import urllib2;
import optparse;
import json;
import httplib2;

#reload(sys)
#sys.setdefaultencoding('utf8');

def Login():

cj = cookielib.CookieJar();
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj));
urllib2.install_opener(opener);

Url = "https://kyfw.12306.cn/otn/passcodeNew/getPassCodeNew?mole=login&rand=sjrand";
resp = urllib2.urlopen(Url);

with open("code.png", "wb") as image:
image.write(resp.read())

codeStr = sys.stdin.readline();
codeStr = codeStr[:-1]

ajax_url = "https://kyfw.12306.cn/otn/passcodeNew/checkRandCodeAnsyn";
dc = {
'randCode' : codeStr,
'rand' : "sjrand"
};
request = urllib2.Request(ajax_url, urllib.urlencode(dc))
request.add_header("Content-Type", "application/x-www-form-urlencoded; charset=utf-8")
request.add_header('X-Requested-With','XMLHttpRequest')
request.add_header('User-Agent','Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36')
request.add_header('Referer','https://kyfw.12306.cn/otn/login/init')
request.add_header('Accept','*/*')
request.add_header('Accept-Encoding','gzip, deflate')

f = urllib2.urlopen(request)
print(f.read())

LoginUrl = "https://kyfw.12306.cn/otn/login/loginAysnSuggest";
dc = {
'randCode' : codeStr,
'userDTO.password' : "你的密码",
'loginUserDTO.user_name': "你的账号"
};

PS：运行出错的话按照报错稍微调整一下，应该没问题，之前我用来查票的。
